Die Berücksichtigung sämtlicher Faktoren erfordert

This is a sentence starter. You use it to set the stage for a requirement. Usually, you follow it with a noun. For example, it might require Zeit (time) or Geduld (patience). You are basically saying: 'Because this is complex, we need X.' It sounds very smart in a presentation. Use it when you want to sound authoritative. It commands respect in a conversation.

Use this in a professional setting. It’s perfect for business meetings or academic papers. You can also use it when making big life decisions. Think about buying a car or choosing a university. It works well when you need to justify a delay. 'Why isn't it done?' 'Well, the consideration of all factors requires more time!' It makes your delay sound like a sign of quality.

Don't use this at a party. If a friend asks if you want a beer, don't say this. You will sound like a robot or a lawyer. Avoid it in very casual texts. It’s way too heavy for small talk. Don't use it with children either. They will just look at you with confusion. Keep it for moments that actually involve complexity.

This phrase perfectly captures the German concept of Gründlichkeit (thoroughness). Germans take pride in being detailed and precise. In German culture, rushing a decision is often seen as a weakness. Taking your time to analyze everything is a virtue. This phrase is the linguistic embodiment of that cultural value. It’s very common in high-level German bureaucracy and law.

You might hear Unter Berücksichtigung aller Umstände (considering all circumstances). Another one is Man muss alle Faktoren einbeziehen (one must include all factors). If you want to be slightly less formal, use Alles muss bedacht werden. However, sämtlicher is the 'gold standard' for total completeness. It sounds much more 'C1' than just saying aller.
